Chargers lose a third LB to knee injury

The transaction is getting tired at Chargers Park.
On Wednesday, the team declared its latest player lost to a knee injury, as outside linebacker Devan Walker was placed on injured reserve. The undrafted rookie follows fellow linebackers Melvin Ingram (Physically Unable to Perform list) and Jonas Mouton (IR), both of whom suffered a torn anterior cruciate ligament in practice sometime since May.
Wide receiver Danario Alexander tore his right ACL on Tuesday. He has yet to be placed on IR.
Walker suffered a torn lateral meniscus, less severe than an ACL, during an 11-on-11 drill in practice on July 31. If an injury settlement is reached, he could theoretically be re-signed this year after he gets healthy, most likely joining the practice squad.
Health-wise, the Chargers enter Thursday's preseason opener on something of a losing streak.
This brush with injuries isn't for a lack of placing importance on health; proper technique and other preventative measures have been the stressing point for Kent Johnston and the new Chargers strength and conditioning staff. For added emphasis, Johnson has a quote painted on the weight room wall in blue, capital letters: "Durability is more important than ability."
And these injuries would at least seem unrelated to the new practice field installed in the offseason. It is made of natural grass. According to a 10-year study by the NFL’s Injury and Safety Panel that was published last year in the American Journal of Sports Medicine, there was found to be a 22 percent higher incident rate for ankle and knee sprains and 67 percent higher rate for ACL sprains on FieldTurf as opposed to grass.
Maybe it is the luck element to the NFL.
As injuries go, someone has to step up. Sixth-round pick Tourek Williams and Frank Beltre are the other rookie outside linebackers on the roster.
